The criteria to assess the origin of magnetite are of prime importance because of their
significance as biomarkers for extraterrestrial life and paleoenvironmental indicators. It is still …

Magnetotactic bacteria (MTB) preserved in sediments (magnetofossils) are highly sensitive
to environmental and climatic forcing and can therefore be used as an easy-to-measure …

Reductive dissolution of magnetite is known to occur below the Fe-redox boundary in
sediments. In this study, detailed processes associated with biogenic magnetite dissolution …

Magnetotactic bacteria perform biomineralization of intracellular magnetite (Fe3O4)
nanoparticles. Although they may be among the earliest microorganisms capable of …

The magnetic signals of magnetite nanoparticles (NPs) preserved in rocks, soils, and
sediments are effective index for paleoenvironmental reconstruction. It has been …

Microbialites–layered, organosedimentary deposits–exist in the geologic record and extend
back in deep time, including all estimated times of inner core nucleation. Microbialites may …

MTB population dynamics and their contribution to iron cycling in modern chemically
stratified environments have not been previously evaluated in a systematic fashion. Using …

Magnetotactic bacteria (Fig. 5.1 AE) are micro-organisms which feel the torque of the Earth's
magnetic field because they produce strongly magnetic particles of magnetite or greigite …

Single‐domain magnetite particles produced by magnetotactic bacteria (MTB) and aligned
in chains, called magnetosomes, are potentially important recorders of paleomagnetic …

Distinct magnetic properties of marine sediments that record the Palaeocene–Eocene
thermal maximum (PETM) have been suggested to be due to a bacterial magnetofossil …
